Piezo Fan for Thermal Management of Electronics

In order to satisfy the demand for light-weight, low power consumption, and compact-sized personal computers, portable electronics, LED applied products and audio electronics, we have developed a 'piezo fan' that works on a different principle from that of motor fans. By using the finite-element method for design support, the demands for long life and compact size were achieved. Also, on the basis of the supposed application, the cooling effects and the cooling possibilities of piezo fans were confirmed by applying them to the heat sources of personal computers, portable electronics, and LED applications.
